The invention relates generally to toys and primarily seeks to provide anovel free flying projectile in the form of a toy rocket bomb which ispropelled through the air by arapidly expanding gas released from acartridge carried by the bomb.

Anobject of the invention is to provide a toy rocket bomb devicecomprising, in combination, a streamlined hollow shell-like bomb elementhaving flight'stabilizing fins at itstail end and provision forfrictiona'lly retaining therein-a compressed gas containing cartridge,and a flight launching and guiding stick having provision-for puncturingthe cartridge to permit the gas to be discharged therefrom and from thetail of the bomb element to initiate and sustain the flight 7 thereof.

Another object of the invention is to provide a hollow shell-like bombelement of the character stated having internally projecting,longitudinally extending, circumferentially spaced ribs thereineffective to engage and frictionally hold a gas cartridge within theelement inposition for facilitating smooth flight of the element, saidribs also being engageable with the exterior of the launching stick in amanner for definitely determining the direction of flight of theelement.

Another object of the invention is to provide a bomb element of thecharacter stated in which the internal ribs terminate short of the tailend of the element, and the interior wall of the element at the tail endportion is constricted slightly'to concentrate the escaping gasandfacilitate the jet propulsion efiect thereof, the minimum diameter ofsaid wall corresponding to the circle in which the inner walls of theribs lie, thereby to cooperate with said ribs in the flight guidingcontact with the launching stick;

With the above and other objects in view that will hereinafter appear,the nature of the invention will be more clearly understood by referenceto the following detailed description, the appended claims, and theseveral views illustrated in the accompanying drawings.

trating a gas cartridge and the launching stick in place just prior to alaunching of the bombelement-in flight, a portion of the end of thelaunching stick being broken away and in section.

Figure 7 is a detail perspective view illustrating a. gas-cartridge.

In the practical development of the invention, there is provided a toydevice comprising three elements, namely the bomb element, the launchingstickand the propelling gas cartridge.

The launching stick is formed in two parts, one comprising acylindricalbody 5 having a cylindrical cavity or bore 6 in its top endinto which a sharp pin 'i' projects, the body of the pin being embeddedin the stick as at 8. The body 5 also has a bore 9 inits lower end intowhich the smaller diameter mounting stick I 0 may be removably inserted,and the lower end of the stick portion l0 may be sharpened as at H sothat the launching stick structure may be mounted erect, or at a desiredangle by insertion in the ground in the manner indicated in Figure 1.

The bomb element generally designated I2 preferably isformed of moldedplastic but may comprise alight hollow shell formed of other suitablemateriaLsuch as light weight metal. When the element I2 is formed ofplastic, it is preferably constructed of three sections secured togetherin end abutting relation by a suitable cement. The central or main bodysection I 3 is in the form of a cylindrical shell having a plurality,four being shown, of inwardly directed, longitudinally extending,circumferentiall-y spaced ribs 3. The ribs extend a short distance fromthe upper end of i the-shell as at I5 as illustrated in Figure 3, and

they similarly extend as at [6 from the lower end of the cylindricalshell and are tapered off in the manner clearly illustrated. Astreamlined nose I! is cemented in abutting relation to the upper end ofthe shell l3 in the manner clearly illustrated in Figures 2 and 3 andsaid nose is formed to include anend socket 18 into which a rubberbumper i9 is inserted.

A tail piece 20 is cemented in abutting relation to the lower end of thecentral shell 53 and is provided with a plurality, four being shown, offlight stabilizing fins 2i. The inner shell Wall is constricted, as at22, and it will be observed that the inner diameter of the tail shell atits lower extremity is the same as the circle in which the inner wallsof the central section ribs It lie. It will also be apparent byreference to Figures 2 and 3 of the drawing that the stabilizing fins.2:! extend a short distance below the end. extremity One of thecompressed gas containing cartridges 24 is shown in place in the bombelement in Figure 6, and in detail in Figure 7, and in theseillustrations it will be apparent that each said cartridge includes acylindrical main body portion having a half-rounded end portion 25 atone end extremity thereof. At its other end the cartridge is reduced indiameter as at 26 and terminates in a reduced diameter cylindricalportion 21 of a size for fitting within the cavity or bore 6 formed inthe top end of the launching body stick 5. The cartridge may be of thetype well known in the home carbonization of beverages and containinghighly compressed CO2 gas sealed within the cartridge shell by thereadily puncturable soft metal seal 28 secured in the reduced diameterend portion 26.

When it is desired to launch the toy rocket, the launching stick may beassembled in the manner illustrated in Figure 1 by suitably insertingthe lower end of the stick H1 in the ground and the upper end thereof inthe receiving bore 9 in the lower end of the cylindrical stick body 5. Acartridge such as is shown in detail in Figure 7 is then inserted in thebomb element with the rounded end extremity 25 thereof centered in thenose I1 and against the stop provided by the bumper socket l8, and withthe lower end portion of the cylindrical body of the cartridgefrictionally held within the ribs I4. See Figure 6.

By now mounting the bomb element over the upper end of the launchingstick body 5 in the manner illustrated in Figures 1 and 6, and byforcing the same downwardly along the guiding body 5 with sufiicientforce to cause the cartridge end 26 to enter the body bore 6 and causethe pin 7 to puncture the cartridge seal 28, the bomb element may belaunched in the direction guided by the launching stick body 5 and itscontact with the longitudinal ribs l4 and the lower end extremity of thetail shell 20. The rapidly expanding gas released from the punctured endof the cartridge will impinge against the end of the mounting stick body5 and then upon rapidly escaping from the constricted end extremity ofthe tail piece 20 will initiate and sustain free flight of the bombelement by jet propulsion, the fins 2| on said tail piece serving tostabilize the flight.

It will be apparent that the cartridge 24 will be frictionally retainedin the bomb element during flight by its engagement within the ribs 14,and the cartridge is so positioned within the bomb element as to placethe main body of the weight well forward in a manner for facilitatingsmooth flight of the free projectile. It will. be apparent also that theprovision of the cavity or bore 6 in the top end of the launching stickbody 5 and the mounting of the pin 1 therein in the manner illustratedin Figure 6 serves as a safety measure assuring against inadvertentpricking of the fingers of children playing with the toy.

While one form of the invention has been shown for purposes ofillustration, it is to be clearly understood that various changes in thedetails of construction and arrangement of parts may be made withoutdeparting from the spirit and scope of the invention as defined in theappended claims.
